Who’s out to get Klaus? What’s Damon and Stefan’s ‘plan’ for Elena? All will soon be revealed!

Mark your calendars: We’re officially three weeks away from the episode of The Vampire Diariesthat also serves as the backdoor pilot for The Originals, the purposed spin-off that follows Klaus (Joseph Morgan) and his siblings to New Orleans’ French Quarter. The CW just released the official description for the episode, revealing information about the new characters we’ll meet down south.

Let’s start with Marcel (Charles Michael Davis), a “charismatic vampire” who also happens to be Klaus’ former protégé. We learned a little bit about Marcel when Charles was first cast in the role, but now we know that he has “total control over the human and supernatural inhabitants of New Orleans.”

So, basically, the protégé has become the master.

But why does Klaus go there in the first place? According to the episode’s description, Klaus receives a “mysterious tip that a plot is brewing against him in New Orleans … [so he] makes a trip to the town he and his family helped build.”
